Great Canon submission. I'd seen this episode a month or so ago, and David's comment about the episode using its gimmick to have BoJack deal with a character flaw rather than just be "hey I'm a gimmick!" was interesting. Made me think that, intentional or not, the theme of the episode is that sometimes we need to get away from dialog to overcome a character flaw, or more specifically to BoJack, to get away from dialog in order to figure out what it is he's really trying to say to someone else.
edit: one could argue the punchline of the episode implies that as soon as BoJack learns there was an easier way his reaction is "You've got to be kidding..."
:D
